Apple on Wednesday released a slew of updates for iOS, iPadOS, macOS, watchOS, and Safari browser to address a set of flaws it said were actively exploited in the wild.
This includes a pair of zero-days that have been weaponized in a mobile surveillance campaign called Operation Triangulation that has been active since 2019. The exact threat actor behind the activity is not known.
- CVE-2023-32434 – An integer overflow vulnerability in the Kernel that could be exploited by a malicious app to execute arbitrary code with kernel privileges.
- CVE-2023-32435 – A memory corruption vulnerability in WebKit that could lead to arbitrary code execution when processing specially crafted web content.
The iPhone maker said it’s aware that the two issues “may have been actively exploited against versions of iOS released before iOS 15.7,” crediting Kaspersky researchers Georgy Kucherin, Leonid Bezvershenko, and Boris Larin for reporting them.
The advisory comes as the Russian cybersecurity vendor dissected the spyware implant used in the zero-click attack campaign targeting iOS devices via iMessages carrying an attachment embedded with an exploit for the kernel remote code execution (RCE) vulnerability.
The exploit code is also engineered to download additional components to obtain root privileges on the target device, after which the backdoor is deployed in memory and the initial iMessage is deleted to conceal the infection trail.
The sophisticated implant, called TriangleDB, operates solely in the memory, leaving no traces of the activity following a device reboot. It also comes with diverse data collection and tracking capabilities.
